Harrison Barnes scored a season-high 26 points to help No. 5 North Carolina beat Texas 82-63 Wednesday. John Henson added 14 points for the Tar Heels (11-2), who won their fifth straight and avenged last season's last-second loss to the Longhorns. North Carolina went on a 13-1 run to build a double-digit lead midway through the first half and never looked back, turning a 39-23 halftime lead into a 24-point margin late in the game. Barnes was coming off consecutive nine-point performances, but the sophomore looked far more active and assertive against the Longhorns by attacking the rim or posting up on shorter defenders. He made 9 of 15 shots and finished with 10 rebounds, part of UNC's 49-34 advantage on the glass. J'Covan Brown was one of three players with 16 points for Texas (9-3), which shot just 35 percent and never recovered from a slow start. Murray St. 78, Tenn.-Martin 54: Donte Poole scored 15 points and No. 22 Murray State remained unbeaten with a 78-54 victory over Tennessee-Martin in the Ohio Valley Conference opener for both teams. Ivan Aska added 12 points, seven rebounds and three assists to help the Racers (13-0, 1-0) to their best start in 75 years. The only better start was 16-0 in 1935-36. Myles Taylor had 22 points for the Skyhawks (3-11, 0-1), who dropped to 0-3 against ranked teams this season. They lost to Louisville and Mississippi State. Murray State is one of six Division I teams without a loss. The Racers led the all-time series with Tennessee-Martin 39-3 and are 22-0 at home against the Skyhawks. Murray State shot 65.2 percent from the field in taking a 36-16 halftime lead. The Skyhawks shot just 23.3 percent in the opening 20 minutes. In another game, Aaron Broussard scored a career-high 29 points and Sterling Carter added 17, but Seattle couldn't complete its rally from 14 points down in the final 8 minutes, and No. 24 Virginia held on for an 83-77 victory.
